Try
talking to A.L.I.C.E.
just like a real person, but remember you are really chatting with a machine! A.L.I.C.E.'s Alicebot engine utilizes AIML (Artificial Intelligence Markup Language) to form responses to yourquestions and inputs.

Unlike other commercial chat robot software costing thousands of dollars, the Alicebot engine and AIML are freely available under the terms of the
GNU General Public License
(used by GNU/Linux and thousands of other software projects).
The A.L.I.C.E. project includes hundreds of contributors from around the world.
